1 Claim. (01. 122-359) This invention relates to an improved boiler, from the burners toward thesmoke pipe ll. The

. particularly adapted for household purposes but may be made for power purposes. The invention resides in the economical structure and its com- 5 pact arrangement of parts.

A further advantage is a construction that provides for a ready assembly of the various parts that form the boiler and the ready disasscciation of parts possible for the purpose of repair or replacement.

The construction provides a boiler that is enicient and will be therefore economical in its operation.

The invention is illustrated in the accompanyl ing drawings. Figure 1 is a side view of the boiler shown inside a casing which casing is in section, as it is inall the other figures. Figure 2 is a section on line 2-2 in Figure 1. Figure 3 is a section on line 3-3 in Figure l but with the side I 8) plates in elevation. Figure 4 is a section on line 4-4 in Figure 1. Figure 5 is a fragmentary perspective View of a part ofone of the side plates.

The boiler is encased in any suitable form of casing and I show a conventional casing ID with 25 a smoke pipe I I and provided at the bottom with burners l2 supplied by the feed pipes 13. The illustration shows gas burners provided with outlets The boiler is mounted above the burners. 30 boiler comprises top headers l5 and bottom headers l6, one on each side. The top header and bottom header on the same side are, in each in= I stance, connectedby coils. The coils I! are thus arranged vertically and are spaced to insure the 35 coils of the opposite sides to alternate, as this is preferred. The coils I1 on each side have their outer loops l8 extended beyond the headers l5 and [6 on the other side. The coils are also maintained in position by the side plates 19 which 40 plates extend between the headers on the same a side and are provided with openings 20 in the form of slits which receive the coils. The plates thus hold-the coils in separated positions and with the reaches in each coil held in aligned relationship. The side plates I9 also form a flue or passage for the major portion of the heat 7 The I side plates,l9 are placed vertically and are preferably spaced to include the headers insidethe heat passage. The plates l9 are held in position by any suitable means and I illustrate the tie-" 5 bolts 2| as such means. "The boiler, also includes a superheater which is supplied from the'upper headers I5. The headers feed into tubes 22 which are connected to a manifold 23, usually by union'connections 24 for easy'assembly and taking down. The manifold 23 has pipe connections which feed the superheater pipes 25 which pass downwardly and then along under coils I'Ljthat is, closeto the burner or burners l2 and within-the space dimensions betweenthe side plates I9.

The pipes feed into a second manifold 26 whichhas the outlet pipe or pipes 21 which are 1 connected to the heating system of a building or I other installation and may be connectedto a 20 drum 2% in case the system is constructed to uti" lize steam. I The inlet pipe or pipes 29 are connected to the I lower headers I6 at the end opposite thati at' which the manifold is located. I

Various changes can be madein the dimensions and proportions of parts without departing from the scope of this invention. 1 I

I claim: v

A boiler comprising opposed parallel bottom 30 headers and opposed parallel topheaders, vertically arranged zig-zag tubes connecting the headers on each side, connections between the top headers, including a manifold and pipes extending from said manifold downwardly adja-. cent the tubes and then extending under said tubes the length of the assembled tubes and a second manifold to which-the said pipes extend, inlet pipes for the lower headers, and outlet pipes for the second manifoldand side plates extend- -ing from each top and bottom header on the same side, said plates having slots to support the end loops of the tubes, said plates forming a passage. between the headers on opposite sides.
